Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transport device that utilizes a motorized crawler-type traveling working machine such as a combine harvester or a harvester that has a threshing device mounted on the machine stand.

Conventionally, it is generally known that after removing the threshing device of these traveling working machines, the machines can be used as self-propelled vehicles. However, the conventional usage method is
The space left after the threshing device on the machine was removed was used to create an enclosure, and cargo could only be placed and transported inside the enclosure. or,
When some type of power work was to be carried out, a dedicated prime mover was installed and used separately.

In addition to making effective use of the large space after removing the threshing device on the machine platform, the present invention enables the use of a simple work platform to utilize the power of the prime mover that is originally provided for driving the transporting device and loading the cargo to be transported. It is designed to be usable for both work such as unloading, and in particular, it utilizes a traveling working machine equipped with a threshing device, and the platform is integrally equipped with at least a support and a winch driven by the prime mover. This unitized and wider work platform can be mounted on and removed from the machine base with a simple operation, and can be quickly attached to and removed from the machine base and connected to the power transmission device of the prime mover. As a result, it is possible to secure a wider loading space than before, and to improve adaptability to a wide range of tasks.In addition, it is possible to replace the threshing device part, which is more easily broken than other parts, with a worn-out combine harvester or harvester. This also increases the effectiveness of post-use.

In an embodiment of the present invention, the above-mentioned transporting device is used as a material collection and transporting device for particularly large pieces of lumber, and
To explain this using drawings, A in FIG. 1 is a self-propelled vehicle after removing a threshing machine C etc. from a harvesting traveling machine such as a combine harvester or a harvester. As will be explained in detail, the focus is on the fact that the self-propelled vehicle has a related configuration as shown in Figure 1, and B is the power type vehicle mounted on the base of the self-propelled vehicle. It is a work platform.

First, to explain the self-propelled vehicle A, reference numeral 1 in the figure is a machine base supported by a crawler 2, and a transmission case 3 for driving the crawler 2, an engine 4, and an operating section 5 are installed at the rear of one side. It is set up.
The output shaft 4a of the engine 4 and the input shaft of the transmission case 3 are connected by transmission with a belt 6, and levers 5a for controlling forward and backward movement, stopping, rotation, etc. are supported on the operating section 5. In this way, the self-propelled vehicle A is realized as a self-propelled device that includes the machine base 1 that is constructed of a relatively wide frame that is strong and stable.

Next, the work platform B of the power working equipment mounted on the machine platform 1 will be explained. Reference numeral 8 is a platform that is larger than the machine platform 1, and is biased towards the rear of one side of the machine platform 1. It is formed in a large area with only the parts such as the mission case 3 placed close to each other missing.
It is detachably mounted on the machine base 1 with bolts 9. Reference numeral 10 denotes a winch, which rotatably supports a drum 12 for winding wire 11. As shown in FIG. It is located adjacent to. The V-belt 14, which is suspended between an input pulley 13a provided on an input shaft 13 for transmitting the drum 12 of the winch 10 and an engine pulley 4b provided on the output shaft 4a of the engine 4, has a tensioned upper side. A tension pulley 15 is provided at one end of a clutch lever 16 that is pivotally supported on the frame of the winch 10. When the clutch lever 16 is actuated, the upper side of the V-belt 14 is pressed or released from above to tighten and loosen the V-belt 14, thereby producing a clutch action. is configured to take place. When the tension pulley is installed on the slack side as in the past, the clutch engages and engages slowly, but the clutch constructed as described above engages and engages extremely quickly and reliably, and can be easily engaged by lever operation. As a result, a half-clutch state can be reliably obtained, and this half-clutch state can be used to operate the brake of the winch. Reference numeral 17 denotes a support that is erected near the winch 10 device, and includes a rear stay 18 and a side stay 19.
It is strongly reinforced. A fixing hook 20 is provided at a location slightly lower than the top of the column 17. Further, the upper part of the support column 17 is formed into a pipe shape, into which an auxiliary support column 17a is fitted so as to be vertically adjustable and fixed, and 17b is a fixing bolt thereof. Reference numeral 21 designates one or more cylindrical bodies that are rotatably fitted onto the auxiliary support column 17a, and includes a flexible hook 2.
2 is provided protrudingly.

When a wire or pulley 23 is hooked onto the flexible hook 22, the hook 22 rotates in the direction of the line of action, so that the hook 22 and pulley 23 can be smoothly rotated without being damaged by excessive force. It has been devised so that it will work. A center hook 27 is provided at the front of the loading platform 8 at a position facing the widthwise center of the drum 12, and is used by hooking the wire 11 or pulley 23 together with the aforementioned fixed hook 20, flexible hook 22, etc. It's becoming like that.

Generally, in order to wrap the wire 11 around the drum 12 in an orderly manner overlapping the entire width of the drum, a pulley 23 is provided in front of the center of the width of the drum 12, and the wire 11 is wound around the drum 12 through the pulley 23.
Since it has to come in from a direction perpendicular to the two axes, conventionally a stake was driven into the ground at a position that met the above conditions and a pulley was hooked to it. Since this can be done by using the center hook 27 on the loading platform 8 as described above, it is possible to greatly save the labor and time for pile driving, centering, etc. Numerals 24 and 25 are sleepers installed horizontally at the front and rear of the loading platform 8, and are screwed onto the loading platform 8 with bolts 26.

Next, the functions and effects of the present invention will be explained. Self-propelled vehicle A on work platform B of power working equipment
To install the platform, place the loading platform 8 on the machine platform 1 and tighten the bolts 9.
The V-belt 14 can be suspended between the engine pulley 4b of the engine 4 and the input pulley 13a of the winch 10, and the relative position between the engine pulley 4b and the input pulley 13a is precisely determined by the bolt 9. When assembling, it can be quickly and reliably assembled without requiring adjustments such as centering. When using the wood collecting and transporting device assembled in this way, for example, when collecting logs on the side of the machine body and loading them onto the loading platform 8, the loading side of the loading platform 8 is connected to the logs as shown in FIG. Stop towards the side and follow the extension line 11a.
One end of the log is hooked onto the adjustable hook 22, and the other end is tied to a fixed object X on the opposite side of the log. Then, the wire 11 pulled out from the drum 12 is tied to the log through a pulley 23 suspended from a flexible hook 22 different from the above, and when the clutch lever 16 is operated to engage the clutch, the wire 11 is wound around the drum 12. The logs are gathered up to the vicinity of loading platform 8. After stabilizing the log, cut the clutch, remove the wire 11 from the log, wrap it around the center of gravity of the log, and attach the end of the wire 11 to the fixing hook 2 as shown by the chain line.
0 and then put the clutch in again, wire 11
The logs are pulled up and pulled up to sleeper 2 on loading platform 8.
Loaded onto 4,25. During this loading, there are struts 17 and stays 18 between the loading platform 8 and the winch 10 device, etc., and these protect the winch 10 device, etc., so even if the logs swing, the winch 10
It will not cause damage to equipment etc. When collecting and loading logs from the rear of the machine, as shown in FIG. 6, the tracing line 11a is supported by a fixed object When the wire 11 is passed through the pulley 23 hooked on the center hook 27 of the wire 11, and further passed through the pulley 23 suspended from the swivel hook 22, and the tip is tied to a log and the clutch is engaged, the wire 11 is collected to the rear.

Therefore, after the raw wood is brought into a stable state, the clutch is once released, the knot position is changed as appropriate, and the clutch is engaged again, so that the raw wood is loaded onto the loading platform 8. As shown in Fig. 7, the loaded logs can be tilted with respect to the longitudinal direction of the machine to bring the center of gravity P of the logs closer to the winch 10, thereby improving the stability of the machine during transport. It is. In the above-mentioned work, the driver operates the clutch at a position close to the clutch lever 16, which is away from the loading side, so that the work can be performed safely.

As described above, the present invention provides a loading platform for use as a self-propelled vehicle after removing the threshing device of a motorized crawler-type traveling working machine such as a combine or a harvester in which the threshing device is mounted on the machine platform 1. A work platform B larger than the machine platform 1 is integrally installed at one end of the machine platform 8 with at least a support column 17 and a winch 10 driven by the prime mover of the traveling work machine. Since it is removably mounted on the platform 1, it can be used as a transport device while making use of the operability and functions inherent in crawler-type traveling machines equipped with a threshing device, such as combines and harvesters. In the event that
Since it is possible to realize a device that is simpler, more stable, and has better operability, it is possible to secure a wider loading space as a transportation device than before, and also to handle large or heavy objects that are impossible for humans to load and unload. It not only makes it possible to easily load and unload even objects, increasing its adaptability to a wide range of tasks, but also makes it possible to reuse a traveling machine with a worn-out threshing device. By transmitting the power of the prime mover used in the work equipment to the winch, there is no need to install a separate prime mover for tasks such as loading and unloading the cargo to be transported. Since it is integrated into a unit, it is possible to produce practical effects such as attaching and detaching the threshing device to the removed machine base and connecting the prime mover to the power transmission device accurately and easily. It is something.

Although the winch of the present invention has been described for loading and unloading work, it goes without saying that it may be used for other work as long as the winch can be used for the work.
